Cooling down an overheating Modem, help needed

post #1 of 4
Thread Starter 

My modem is a run-of-the-mill Vodacom K3772-Z

 

the problem i'm having is when ever significant data is being exchanged the thing heats up real fast. witch is a real pain while playing Crysis 3 online...

 

I have not been able to take surface temps where the sim card slots in but if i had to guese it would be well in the 50*C range, at witch point it starts to "behave", loosing connection and what-not

 

The area where most of the heat, if not all is ,is 15mm by 20mm in size

 

I've been wondering if there isn't some sort of cooler that i could mount on it?

Yes you can mod it to fit a fan, it has been done before. When I played only console multiplayer on xbox (original) my modem would heat up so I would take a bag of frozen peas and put it right on top of it and it did the trick too, if not I would at least put a house fan blowing air on it and make sure that it is in an open space.

Just to be sure, we're talking about a Vodaphone USB pre-paid modem?

If this is the case I think the first thing I'd suggest is to get a very short USB extension dongle with exposed metal shielding on the socket end. That'll probably double the air cooling capacity. Then you can get a little tiny desk fan and use a twist-tie or pull-tie to crucify it on the front to the side of the center of rotation. This will likely resolve the issue in two ways, by cooling AND by making it impossible to maintain a connection.

Use the short dongle and stick it up in a paper or cardboard tube using a couple twist ties so it stays centered then hang that up from the other end. It should act like a cooling tower once it gets warmed up.

Trying not to giggle.

Third option is to pop El Inútil open and stick a small heat sink onto it, for this circumstance a little superglue and some aluminum from a turkey/duck pan would probably be sufficient.

However we can approach the heat issue from the other direction.


What all are you running near it that can cause electrical interference? Its clearly having to use a high power mode in order to communicate. You can likely use a five foot USB cable to get it away from your computer and someplace to the side where it is receiving less noise, thus will need less power.

So a combo of all should suffice. I'd bet you'd have the first fully blown hack-sinked remote USB cellular modem in your neighborhood.

I'm gonna go in the kitchen now.

prjindigo, you just gave me an idea

 

so my pc is causing the modem to use more power than is should be? Makes sense to me since i have it directly connected to the usb port

 

also have a desktop fan to blow air past the overheating modem partially solves the problem,

 

prjindigo, you just gave me an idea, here it is: I'm going to se if i can mod my ref intel cooler (i use a H100i now) to fit in the source of the heat and fastening the whole thing with some cable ties. My arguement was: if it can keep a core i7 happy, it would certainly keep a modem happy, or i could simply solder a piece of copper to the base of the cooler so i dont need to trim the base of the ref Intel cooler

 

But first i need to buy some thermal paste/grease first, since somebody stole it ( Thermaltake TG-1) and a usb exstension (i didn't get one with the modem)
